Description

Photoelectrochemical device
TECHNICAL FIELD
This invention relates to photovoltaic (PV) devices and more particularly, but not exclusively, to photoelectrochemical photovoltaic devices.
Further, this invention relates to methods of manufacturing such devices.
BACKGROUND TO THE INVENTION
A variety of photovoltaic devices are available for conversion of energy of electromagnetic radiation to electrical energy. These include a conventional solid- state devices (see M. Green Third generation photovoltaics: concepts for high ef- ficiency at low cost, The Electrochemical Society Proceedings, Vol. 2001 -10, p. 3- 18) and more recently developed photoelectrochemical (PEC) devices

Photoelectrochemical devices, as of the type disclosed in the above patents, are capable of being fabricated in a laminate arrangement between two large area substrates. One typical arrangement involves two glass substrates, each utilising an electrically conducting coating upon the internal surface of the substrate. At least one of said first and second substrates is substantially transparent to visible light, as is the attached transparent electrically conducting (TEC) coating. PEC cells contain a working electrode, typically comprising a dye-sensitised, nanoporous semiconducting oxide (e.g. titanium dioxide known as titania) layer attached to one conductive coating, and a counter electrode, typically comprising a redox electrocatalyst layer attached to the other conductive coating. An electrolyte containing a redox mediator is located between the photoanode and cathode, and the electrolyte is sealed from the environment.
Many photoelectrochemical devices would be advantaged by an increased size of the modules. However, the TEC coatings, which usually comprise a metal ox- ide(s), have high resistivity when compared with normal metal conductors, resulting in high resistive losses for large area photoelectrochemical cells, which affects the efficiency of the device especially in high illumination conditions.
Electrical resistance of substrates can be reduced by using metal plates, foils or metal mesh. Most of metals commonly used, however, are chemically reactive with the electrolyte of the photoelectrochemical cells. Corrosion of metallic components of PEC cells had been recognised as a major limitation to successful commercialisation of PEC devices for many years.
In one arrangement the photoelectrochemical cells are connected in series, internally within a single module. Metallic conductors are used for such interconnection. Once again, choice of metallic conductors is limited to platinum and similar metals, titanium and tungsten because of chemical interactions with the typical iodide containing electrolyte of a photoelectrochemical cell.
It is therefore an object of the present invention to provide a protective coating for low cost metallic conductors used in the photoelectrochemical cells that will solve the combined problem of effective corrosion resistance without loss of effective performance while still being cost effective. SUMMARY OF THE INVENTION
In accomplishing the foregoing and related objectives, the invention provides for using layers of electrically conductive but chemically inert materials (e.g. diamond and electrically conducting nitrides and carbides) layers to conduct electrical current inside photoelectrochemical cell while protecting metallic components of the photoelectrochemical cell. It has been discovered that thin layers of these materials provide sufficient conductivity to electrically connect highly conductive metallic components, at the same time these materials are chemically inert towards electrolytes utilised in PEC. The electrical conductivity of the protecting layer can be modified by variation of composition or thickness so that the layer can be opti- mised for different applications (e.g. light conditions).
The protective layers could be deposited using any known technology for their formation (e.g. arc deposition, sol-gel, sputtering, CVD, etc.). The layer is required to be sufficiently electrically conductive to enable viable electrical output while being chemically inert toward components of the photoelectrochemical cell.
Considering conductive properties of such layers, the invention also provides for these layers being formed directly on substrate (glass, polymeric materials) without an intermediate metallic component, when requirement for electrical conduc- tance are not high (e.g. - for low light conditions or small cell size).
This invention is based on realisation that some materials such as titanium nitride form pinhole free strongly bound coatings that protect metallic conductors and, at the same time, provide electrical conductivity sufficient for successful operation of PEC device. Our experiments demonstrated that although unprotected 316 stainless steel substrate corrodes within several days of operation at room temperature, causing irreversible damage to electrolyte of the PEC device, a thin and dense layer of TiN coating deposited on the same substrate ensures many months of successful operations at 75 °C. Further analysis demonstrated that certain non-metallic materials satisfy requirements of corrosion protection and electrical conductivity by way of a several micron thick film.
These include: diamond and semimetallic, metallic (and multimetal) nitrides, car- bides, oxides, borides, phosphides, suicides, antimonides, arsenides, tellurides and combinations thereof (e.g oxynitrides, arsenide sulphides).
Still preferred materials for the purpose of this invention are: titanium nitride (TiN), zirconium nitride and boron carbide.
Further preferred materials include suicides of niobium, molybdenum, tantalum, tungsten or vanadium.
While this invention provides for a range of certain materials to be used for pro- tection of the said metallic conductors, further description uses TiN as an example.
In accordance with one aspect of the invention a TiN layer is deposited on metal foil or plate (e.g. stainless steel foil), thus protecting the foil from electrolyte of the cell.
The foil or plate serves as a substrate for either working or counter electrode of the photoelectrochemical cell.
In accordance with another aspect of the invention a TiN layer is deposited on metallic mesh, used to conduct electrical current generated locally inside a cell to the external terminals. The mesh could be used in either or both working or/and counter electrodes of a photoelectrochemical cell.
In accordance with a further aspect of the invention, a TiN layer is deposited on metallic conductor used to interconnect photoelectrochemical cells in a series connected module. In this case both the working electrode and the counter electrode are divided each into electrically isolated portions, and the said metallic conductor connects at least one portion of the working electrode to a portion of the counter electrode
